Kevin Kouzmanoff got back to the majors for the first time since 2011 and hit .362 with a 1.029 OPS in 13 games for the Rangers filling in for the injured Adrian Beltre … and now he’s hurt too.

Kouzmanoff has been placed on the disabled list with a herniated disk in his back and T.R. Sullivan of MLB.com writes that “it hasn’t been determined if he will need surgery.”

Texas is expected to activate Beltre from the disabled list tonight anyway, so it’s unclear how much playing time Kouzmanoff would have gotten going forward, but it’s an awfully tough break for a guy who had a chance to get his career back on track.

Paxton, 30, has been among the game’s better starters over the past few years. In 2018, he went 11-6 with a 3.76 ERA and a 208/42 K/BB ratio in 160 1/3 innings. The lefty has two more years of arbitration eligibility remaining after earning $4.9 million this past season.

Sheffield, 22, is the headliner in the Mariners’ return. He made his major league debut in September for the Yankees, pitching 2 2/3 innings across three appearances. Two of those appearances were scoreless; in the third, he gave up a three-run home run to J.D. Martinez, certainly not an uncommon result among pitchers. MLB Pipeline rates Sheffield as the Yankees’ No. 1 prospect and No. 31 overall in baseball.

Thompson-Williams, 23, was selected by the Yankees in the fifth round of the 2016 draft. This past season, between Single-A Charleston and High-A Tampa, he hit .299/.363/.546 with 22 home runs, 74 RBI, 63 runs scored, and 20 stolen bases in 415 plate appearances. He was not among the Yankees’ top-30 prospects, per MLB Pipeline.

Swanson, 25, was selected by the Yankees in the eighth round of the 2014 draft. He spent most of his 2018 campaign between Double-A Trenton and Triple-A Scranton/Wilkes-Barre. Overall, he posted a 2.66 ERA with a 139/29 K/BB ratio in 121 2/3 innings. MLB Pipeline rated him No. 22 in the Yankees’ system.

This trade comes as no surprise as the Yankees clearly wanted to upgrade the starting rotation and the Mariners seemed motivated to trade Paxton this offseason. To the Mariners’ credit, they got a solid return for Paxton, as Sheffield likely becomes the organization’s No. 1 prospect. The only worries about this trade for the Yankees is how Paxton will fare in the more hitter-friendly confines of Yankee Stadium compared to the spacious Safeco Field, and Paxton’s durability. Paxton has made more than 20 starts in a season just twice in his career — the last two years (24 and 28). The Yankees are likely not done adding, however. Expect even more new faces before the start of spring training.
